Swift's defer statement is useful for cleanup logic. It guarantees that a block of code runs when the current scope exits, regardless of whether execution completes normally, throws an error, or returns early.
Before Swift 6.4, we couldn't perform asynchronous operations directly inside a defer block. Starting with Swift 6.4, it is possible.
When working with SwiftUI, we constantly compose views from other views.
A Text view can be placed inside a VStack, a VStack can be embedded in a NavigationStack, and an entire screen can become a child of another view. This ability to build complex user interfaces from smaller building blocks is one of the core ideas behind SwiftUI.
Before an iOS app can receive remote notifications, we first need to register the app with Apple Push Notification service (APNs). This process includes requesting notification permission from the user, registering with APNs, and handling the generated device token.
In this article, we'll look at how to set up push notification registration in a SwiftUI app.
When developing iOS apps, we often need to persist sensitive user data such as passwords, authentication tokens, or cryptographic keys.
For this type of data, storing values in plain files or UserDefaults is usually not appropriate. Instead, iOS provides the Keychain Services API, which stores sensitive data in an encrypted and system-managed database.
In this article, we'll look at how the Keychain API works and how to save, retrieve, update, and delete keychain items in Swift.
SwiftUI provides built-in support for animations. In many cases, adding animations only requires attaching an animation to a state change.
There are two common ways to do this:
In this article, we'll look at how both approaches work and when to use each of them.
